STS-57 MS2 Sherlock operates RMS THC on OV-105’s aft flight deck

STS057-31-030 (25 June 1993) --- Astronaut Nancy J. Sherlock operates Endeavour's remote manipulator system (RMS) during the June 25 extravehicular activity of two crewmates. At one point, astronaut G. David Low, while his feet were anchored to a special restraint device on the end of the RMS arm, moved about, with Sherlock's aid, while holding astronaut Peter J. K. (Jeff) Wisoff. The activity represented an evaluation of techniques which might be used on planned future missions -- a 1993 servicing visit to the Hubble Space Telescope and later space station work -- which will require astronauts to frequently lift objects of similar sized bulk.
